CLOTH-NAPPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 4,010, dated August 29., 1893. Application filed August 19, 1892. Serial No. 443,502. (No model.) i

To @ZZ whom it may concern:

Be it known that I, MILTON M. WILSON, a citizen of the United States, residing at Camden, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in Cloth-Napping Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in machines for forming nap on cloth and it consists in certain novel features hereinafter described and claimed.

In the annexed drawings, which fully illustrate my invention, Figure l is a side elevation, partly broken away, of my improved machine, and Fig. 2 is a front elevation of the same.

In carrying out my invention, I employ a supporting frame A which may be of any desired construction and upon said frame I erect the standards B which are provided with the vertical slots or guides C, as shown.

The napping rollers D are arranged in pairs and consist of cylinders or cylindrical blocks journaled in the standards and provided, between the same, with the teeth E adapted to engage the surface of the cloth and form the nap in the operation of the machine. I have shown two pairs of napping rollers, one pair on each side of the guides C, and prefer to use that arrangement, but one pair may be dispensed with, or more than two pairs may be used, according to the depth of nap required, without departing from my invention.

Within the guides C, I mount thereciproeating cloth-supporter G which consists of a block provided at its center with ahorizontal slot H and having a wrist pin I at its upper end. This wrist pin is connected, by a pitman J, with the cam or crank arm K on the end of the driving shaft L which is mounted in the upper portions of the standards and is provided with a pulley M by means of which,

and a suitable belt,it can be driven from any suitable motor. A brush roller N is mounted on the driving shaft and bears upon the upper napping. rollers so as to clean the same as they are rotated, and a similar brush roller O is mounted in the supportingframe or the lower portions of the standards and cleans the lower napping rollers in the same manner. The lower brush roller is connected with the driving shaft by a crossed belt P and pulleys F and is rotated thereby as shown.

At a suitable distance from the napping rollers, I provide the guide rollers Q under which the cloth passes and by which it is held smooth. The cloth is held under proper tension on the guide rollers by the pressure rollers R which are mounted in the outer endsof the swinging frames S which are pivoted to thenlpper corners of the standards and serve, by their weight, to hold the pressure rollers down upon the guide rollers.

In practice, the cloth is passed under the rst pressure roller and the first guide roller and then between the napping rollers and through the slot in the vertically reciprocating cloth holder. It is then passed around. the remaining guide roller and pressure roller and over and around the roller T. The machine is then set in motion and the cloth drawn steadily forward by the rotation of the roller T as will be readily understood. When the machine is set in motion, the cloth holder will be caused to reciprocate vertically and the cloth will consequently be forced against the hooked teeth of the napping rollers. The simultaneousforward motion of the cloth will cause it to engage the hooked teeth of the napping rollers and consequently the nap will be drawn out. The napping rollers will be rotated by the cloth in engagement therewith and tearing of the cloth is thereby obviated. It is necessary, however, that the speed of the rollers be lower than the forward speed of the cloth in order to form a nap, and to accomplish this result I providea friction device,

-such as aspring encircling the journal of the napping roller and adapted to bind thereon.'

It is obvious that by adjusting the tension of the springs, the movement of the napping rollers will be retarded to a greater or less degree and the amount of nap formed thereby easily regulated. The brush rollers will be rotated simultaneously with the other parts and will remove all fiber from the teeth o f the napping rollers so that they will be perfectly clean when presented to the cloth.

IOO

It will be seen from the foregoing description that I have provided a very simple and eicient machine by the use of which any desired amount of nap may be formed without moving the filling and the advantages of the machine are thought to be obvious.

Having thus described my invention, what Iclaim, and desire to secure by Letters Patent, is-

l. In a cloth-napping machine, the combination of two pairs of napping rollers, the cloth being adapted to pass between the rollers of each pair and actuating the same, and a reciprocating cloth holder and carrier arranged between the pairs of napping rollers and vibrating the cloth.

2. In a cloth-napping machine, the combination of two napping rollers, the cloth being adapted to pass over and actuating the same, and a reciprocating cloth holder and carrier arranged between the napping rollers and vibrating the cloth. l

3. The combination with the napping rollers actuated by the cloth and the reciprocating cloth holder arranged between the same, of a driving shaft arranged above the holder and having a crank, a pitman con necting said crank with the cloth holder, and a brush roller secured on the driving shaft and engaging the napping rollers.

In testimony whereof I aix my signature in the presence of two witnesses.
